| const VisibilitySubdivision::VisibilityVector & getVV( | const Util::GenericAttribute * | attribute ) |
Convenience function to extract the visibility vector from a GenericAttrbiute.
Parameters
- attribute
- GenericAttribute which is used as source.
Returns
Extracted visibility vector

Defined in MinSG/Ext/VisibilityMerge/Helper.h:58
function
MinSG::VisibilityMerge::Helper::collectVisibilityCells
| public | static |
| VisibilitySubdivision::cell_set_t collectVisibilityCells( | VisibilitySubdivision::cell_ptr | root ) |

function
MinSG::VisibilityMerge::Helper::getRuntime
| public | static |
| VisibilitySubdivision::costs_t getRuntime( | const VisibilitySubdivision::list_ptr | cell ) |
Calculate the overall runtime for a visibility list by calculating the sum of triangles of visible objects from that cell. The result is stored in an internal cache.
Parameters
- list
- Visibility list
Returns
Runtime costs
Defined in MinSG/Ext/VisibilityMerge/Helper.h:77
function
MinSG::VisibilityMerge::Helper::clearRuntime
| public | static |
| void clearRuntime( | const VisibilitySubdivision::list_ptr | list ) |
Invalidate the runtime of the given list in the internal cache. This function has to be called when a list was modified and the runtime might have been changed.
Parameters
- list
- Visibility list
